Brake experts since 1916 When you enter into cooperation with us you obtain a partner that knows its job. We don’t call ourselves brake experts for nothing. We have been in the industry since 1916 and we have always stayed ahead in technical developments, kept both eyes on the demands of the market and established ties with prominent and recognised competent suppliers. What you get from us always maintains top class, whether it’s individual parts or customised systems. Engineered by Rydahls Most of the brake systems we produce are customised. Within our concept “Engineered by Rydahls” we deliver custom-made brake systems that can go straight into your assembly lines. If you bring us in at an early stage of a project we can support you all the way with technical advice and assume responsibility for the entire process – everything from design, brake calculations and dimensioning, to production, tests and delivery of brake systems. Engineered by Rydahls is our signature for the unique brake systems we develop for machinery and vehicles, commissioned by customers from many parts of the world. Top class systems and products Throughout the years we have carefully selected several suppliers that we know well, and whose products we stand for. When we design brake systems it’s our competence in combination with reliable and tested products that interacts and results in unique solutions. One thing that our partners share in common is that they are actively engaged in research and development, and that their products are among the best that can be found on the market. Long-term sustainability We aim to run our business so that we can achieve maximum sustainability. Primarily this means what we can actually control – the consumption of energy, recycling, and modes of transport etc. But we also take the policies of our suppliers into consideration and as far as possible choose partners who share our view of long-term sustainability.

Advanced design and production of brake systems. Our job is to give you a brake solution that is not only one hundred per cent reliable, but which also gives you advantages in your production and in your delivery on the market. It’s often about special solutions. We like to tackle challenges like this because that’s where we get to use all of our competence and innovative capacity, to create a cost-effective and reliable solution for you.
Our offer As in so many other contexts, the start is decisive for the end result. Together with you we go through the necessary requirements and we prepare technical specifications for the system. Stage two is the actual design, with drawings, brake calculations and dimensioning. In stage three we produce the system. The entire process takes place within a jointly agreed timetable for delivery. Advising, design and brake calculations You will find us to be a technical advisor for all types of brake issues. We suggest materials and guide you through obstacles and problems. It’s important to know at an early stage what requirements are set for braking times, braking power and braking torque, so that we can do the correct brake calculations. Designs and drawings It’s just as important to work on the basis of an explict definintion of the environment in which your brake system is going to operate. What does the area look like, what are the dimensions, which adjacent parts and materials do we have to take into consideration in terms of heat and moisture? From the set specifications our design department then produces a CAD drawing that forms the basis for the design. Production of brake systems In our assembly workshop we can handle most requirements for the production of brake systems. Everything from mechanical processing, such as turning, drilling and milling, to the assembly of extra accessories and final assembly of complete brake systems. We also undertake to pack, label and adapt complete assemblies and brake system kits so that they can directly go into your assembly lines or spare part stocks. All systems are inspected prior to delivery. Tests and testing In those cases where as a customer you have an express preference, we can conduct tests of brake systems in our own workshop. We can build up customised functional brake systems in test benches to clearly demonstrate the system for you, for training and to certify circuit pressure and functionality.

Brake systems for machinery and vehicles We design and produce brake systems for most off-road vehicles, e.g. tractors, trucks, forestry machines and construction machinery. We have a comprehensive product range that covers all parts of the brake system. Everything from drum brakes, disc brakes, valves and cylinders, to hoses, nipples and couplings. Hydraulic brakes and brake systems One of our specialities is hydraulic brake systems for semitrailers and custombuilt vehicles. And we are happy to tackle air suspension equipment with load sensing valves. Pneumatic brakes and brake systems We deliver many different types of pneumatic brakes and brake systems, also for agricultural machinery. The brakes are delivered either in parts or as complete pneumatic brake systems, depending on your requirements. We also have the opportunity to deliver brake systems built up of both hydraulics and pneumatics. Electromagnetic brakes and clutches These types of products are used for example in electric trucks, industrial doors and lifts. Axles for farming and forest trailers We have a strong offer of axles. Naturally, we can also take care of the activation no matter if it is pneumatic or hydraulic. Electric throttle controls for off-road machines Diesel engines are steered via electronic hand or foot operated throttle controls on modern off-road machines.

Knott has been our partner for many years. We have developed several different types of brakes together, and today we deliver brakes in many varieties to leading vehicle manufacturers. “We make your brake” is a reasonable motto in this case. Knott’s competence can be trusted. It is a partner that understands you and your projects. The result is a solution that fits all your needs. Knott has a total of more than 2,000 different varieties of brakes to choose from. If that is not enough, a new design can naturally be developed just for you.

TVZ is our partner for axles. It is a mediumsized company with products for the farming and construction machine sector. The company produces axles as well as braked and unbraked stub axles. The production consists to a large extent of modern CNC machines, which guarantees a high and constant quality and great flexibility.
Square axles for 25/40 km/h or 60/80km/h in braked and unbraked variants.
Steering axles for 25/40 km/h or 60/80 km/h in several different variants and designs. Tire wear is normally a heavy expense for vehicles. By exchanging one or several axles to steering ones, the tire wear can decrease significantly. The life of the vehicle’s other components, such as the spring system, will also be extended when using steering axles.
Hydraulic or mechanical brakes that meet most European requirements, for instance TĂœV, ECE-R13 and UTAC.
Stub axles in several different designs suitable for smaller trailers as well as larger forestry and farming trailers.

Electromagnetic brakes are often constructed to work as negative brakes. This means that the brake is activated when the power is switched off. These brakes are often used in different types of electric production, such as electric trucks, electric vehicles, conveyors and other types of industrial applications. We can offer most types of electromagnetic brakes from our partner Vortex. Making customised solutions is not especially uncommon, and it is rarely a problem.
Spring-operated electromagnetic brakes • Available sizes: 37-500 mm in diameter • Torque range up to 1500 Nm • Low-wear • Easy to adjust • Several accessories
Permanent magnetic brakes Dry running Zero-backlash High temperature insulation Flexible mounting Torque range 0.4 Nm - 160 Nm
